BACKGROUND 1. Field of the Disclosure

The present disclosure relates generally to an antenna that performswireless communication with an external device and an electronic deviceincluding the same.

2. Description of the Related Art

An electronic device such as a smartphone, a tablet personal computer(PC), etc., may transmit and receive various data to and from anexternal device. The electronic device may perform long distancecommunication (e.g., mobile communication such as a voice call orwireless data communication), short range communication (e.g., Bluetoothcommunication or wireless fidelity (Wi-Fi) communication), and/orultra-short range communication (e.g., wireless payment, wirelesscharging, or near field communication (NFC)).

Generally, a part (e.g., a side surface or a rear surface) of an outerhousing of an electronic device is implemented using a metal frame,which may be used as a radiator of an antenna for wirelesscommunication. The metal frame may be separated by using a segmentformed by an insulating material (e.g., plastic) at portion thereof,thereby forming an electrical length for wireless communication.

A conventional electronic device may include a plurality of multi-bandantennas to simultaneously transmit and receive signals of variousbands, such as three-carrier aggregation (3CA), 4Rx, 2Tx, etc., (or tooperate in a dual standby state). However, it is difficult to mount aplurality of antennas due to a limitation of mounting space in theelectronic device.

Additionally, when a plurality of antennas are mounted in a limitedspace, communication performance may decrease due to mutualinterference.

Also, when a user grips the electronic device or places his/her headnear an antenna for calling, electromagnetic waves, which may be harmfulto the user, are generated due to an increase in a specific absorptionrate (SAR).

Accordingly, the electronic device 101 may includevarious antennas for executing the communication schemes.

The electronic device 101 may include a plurality of antennas capable oftransmitting and receiving a multi-band frequency signal. Frequencybands of the antennas may be the same as or different from each other.For example, a first antenna may transmit and receive frequency signalsof a high band and a middle band, and a second antenna may transmit andreceive frequency signals of the middle band and a low band.

Alternatively, the first antenna and the second antenna may all transmitand receive a signal of the high/middle/low band and may have differentoperating characteristics. In this case, the first antenna and thesecond antenna may be designed to correspond to a wide-band frequencysignal through complementing each other.

The electronic device 101 includes a display 110 and a housing (or body)120. The display 110 may output a variety of content (e.g., a text or animage). The display 110 may receive an input of a user through a touchinput.

The conductive member 150 may include a plurality of conductive patternsthat are separated through a plurality of nonconductive members.Although the conductive member 150 is segmented into first to fourthconductive patterns 151 to 154 by first to third nonconductive members161 to 163 in FIG. 1 , the present disclosure is not limited thereto.

The first to third nonconductive members 161 to 163 are disposed betweenthe first to fourth conductive patterns 151 to 154. The nonconductivemembers 161 to 163 extend in a direction perpendicular to the frontsurface (the surface on which the display 110 is disposed) or the rearsurface of the electronic device 101.

The first conductive pattern 151 to the fourth conductive pattern 154may operate as a radiator of an antenna for wireless communication. Thefirst conductive pattern 151 to the fourth conductive pattern 154 mayform a plurality of multi-band antennas.

For example, the second antenna202 may use a conductive pattern between the second nonconductive member162 and a first ground part 221.

Referring to FIG. 2A, the first antenna 201 includes the firstconductive pattern 151, the third conductive pattern 153, a firstfeeding part 210, a first ground part 221, and a second ground part 222.The first antenna 201 may transmit and receive a signal of a specifiedfrequency band to and from an external device by using the firstconductive pattern 151 and the third conductive pattern 153.

The first feeding part 210 may connect the first conductive pattern 151with a communication circuit (e.g., a radio frequency (RF) circuit, anRF module, etc.) capable of transmitting and receiving an RF signal. Thefirst feeding part 210 may be a point to which RF signal for anoperation of the first antenna 201 is supplied. The first feeding part210 may be connected to the first conductive pattern 151 between thefirst nonconductive member 161 and a point to which the first groundpart 221 is connected.

The first ground part 221 may be connected to the first conductivepattern 151. The first ground part 221 may be disposed adjacent to thesecond nonconductive member 162. The first ground part 221 may beconnected to the first conductive pattern 151 within a specified firstdistance range from the second nonconductive member 162.

The second ground part 222 may be connected to the third conductivepattern 153. The second ground part 222 may be disposed adjacent to thefirst nonconductive member 161.

The first antenna 201 may operate as an inverted F antenna (IFA)transmitting and receiving a multi-band signal. For example, the firstantenna 201 may be configured to transmit and receive a signal includedin the low band (e.g., an 800 MHz band) or the middle band (e.g., a 1500MHz band).

The second antenna 202 includes the second conductive pattern 152, thefourth conductive pattern 154, a second feeding part 215, a third groundpart 233, and a fourth ground part 224. The second antenna 202 maytransmit and receive a signal of a specified frequency band to and fromthe external device by using the second conductive pattern 152 and thefourth conductive pattern 154.

The second feeding part 215 may connect the second conductive pattern152 with the communication circuit (e.g., an RF circuit, an RF module,etc.) capable of transmitting and receiving an RF signal. The secondfeeding part 215 may be a point to which RF signal for an operation ofthe second antenna 202 is supplied. The second feeding part 215 may beconnected to the second conductive pattern 152 between the secondnonconductive member 162 and a point to which the third ground part 233is connected.

Referring to FIG. 2B, frequency bands of the first antenna 201 and thesecond antenna 202 may be changed or exchanged through switching. Theswitching may be executed through a switching structure connected to thefirst feeding part 210 and the second feeding part 215.

For example, in a pre-switching state (e.g., the state of FIG. 2A), thefirst antenna 201 may be designed to transmit and receive a signalincluded in the low band (e.g., the 800 MHz band) or the middle band(e.g., the 1500 MHz band), and the second antenna 202 may be designed totransmit and receive a signal included in the middle band (e.g., the1500 MHz band) or the high band (e.g., the 2400 MHz band), higher than aband corresponding to the first antenna 201.

If switching is made in the switching circuit, frequency bands of thefirst antenna 201 and the second antenna 202 may be exchanged asillustrated in FIG. 2B. In this case, the first antenna 201 may bedesigned to transmit and receive a signal included in the middle band(e.g., the 1500 MHz band) or the high band (e.g., the 2400 MHz band),and the second antenna 202 may be designed to transmit and receive asignal included in the low band (e.g., the 800 MHz band) or the middleband (e.g., the 1500 MHz band) lower than the corresponding band of thefirst antenna 201.

FIG. 3A is a graph illustrating radiation efficiency of a first antennaand a second antenna before and after switching according to anembodiment of the present disclosure.

Referring to FIG. 3A, the radiation efficiency graph represents a ratioof power of an electromagnetic wave signal radiated from an antenna topower supplied to the antenna.

In a pre-switching state (e.g., the state of FIG. 2A), the first antenna201 may operate in the form of the graph 310. The first antenna 201 mayoperate as a multi-band antenna, and a radiation efficiency associatedwith a signal of the low band (e.g., the 800 MHz band) may be higherthan a radiation efficiency associated with a signal of the middle band(e.g., the 1500 MHz band) or the high band (e.g., the 2400 MHz band).

In a post-switching state (e.g., the state of FIG. 2B), the firstantenna 201 may operate in the form of a graph 311. In the first antenna201, compared with the pre-switching state, a radiation efficiencyassociated with a signal of the low band (e.g., the 800 MHz band) maydecrease (e.g., from −4 dB to −8 dB), and a radiation efficiencyassociated with a signal of the middle band (e.g., the 1600 MHz band)and a signal of the high band (e.g., the 2400 MHz band) may increase.

In the pre-switching state, the second antenna 202 may operate in theform of a graph 320. The second antenna 202 may also operate as amulti-band antenna, and a radiation efficiency associated with a signalof the middle band (e.g., the 1500 MHz band) or the high band (e.g., the2400 MHz band) may be higher than a radiation efficiency associated witha signal of the low band (e.g., the 800 MHz band).

In the post-switching state, the second antenna 202 may operate in theform of a graph 321. In the second antenna 202, compared with thepre-switching state, a radiation efficiency associated with the middleband (e.g., a 1600 MHz band) and the high band (e.g., a 2400 MHz band)may decrease.

A communication circuit in the electronic device 101 may changecharacteristics of the first antenna 201 and the second antenna 202 bychanging a matching value. The communication circuit may adjust animpedance matching value such that each antenna transmits and receives asignal of a necessary frequency band.

FIG. 3B is a graph illustrating a reflection coefficient of a firstantenna and a second antenna before and after switching according to anembodiment of the present disclosure.

Referring to FIG. 3B, the reflection coefficient graph represents achange in an input reflection coefficient according to an antennafrequency. As illustrated therein, a signal of the correspondingfrequency band is received more effectively as an input reflectioncoefficient becomes smaller.

In a pre-switching state, the first antenna 201 may operate in the formof a graph 310 a. In a post-switching state, the first antenna 201 mayoperate in the form of a graph 311 a.

Referring to FIG. 4A, the first antenna 201 and the second antenna 202may be distinguishable from each other with respect to the secondnonconductive member 162. A communication circuit (e.g., a communicationprocessor (CP)) in the electronic device 101 may short-circuit or openopposite ends of the second nonconductive member 162 through a separateswitching structure. In this case, a radiation efficiency of eachantenna may change as the opposite ends of the second nonconductivemember 162 are short-circuited or opened.

The first antenna 201 shows a radiation efficiency change of a graph 410while the opposite ends of the second nonconductive member 162 areopened. The first antenna 201 may transmit and receive a signal of about800 MHz band, in the low band.

The first antenna 201 shows a radiation efficiency change of a graph 411while the opposite ends of the second nonconductive member 162 areshort-circuited. After the opposite ends of the second nonconductivemember 162 are short-circuited, the first antenna 201 may transmit andreceive a signal of about 900 MHz band, in the low band.

The second antenna 202 shows a radiation efficiency change of a graph420 while the opposite ends of the second nonconductive member 162 areopened. The second antenna 202 may transmit and receive a signal ofabout 1700 MHz band in the middle band and may transmit and receive asignal of about 2400 MHz band in the high band.

The second antenna 202 shows a radiation efficiency change of a graph421 while the opposite ends of the second nonconductive member 162 areshort-circuited. After the opposite ends of the second nonconductivemember 162 are short-circuited, the second antenna 202 may transmit andreceive a signal of about 2100 MHz band in the middle band and maytransmit and receive a signal of about 2700 MHz band in the high band.

The communication circuit in the electronic device 101 may connect andseparate the opposite ends of the second nonconductive member 162through a separate switching structure such that the first antenna 201and the second antenna 202 operate in various frequency bands. Thecommunication circuit may adjust an impedance matching value such thateach antenna transmits and receives a signal of a necessary frequencyband.

FIG. 4B is a graph illustrating a reflection coefficient change of anantenna according to a short or open state of a second nonconductivemember according to an embodiment of the present disclosure.

Referring to FIG. 4B, the first antenna 201 and the second antenna 202may be distinguishable from each other with respect to the secondnonconductive member 162. The communication circuit in the electronicdevice 101 may connect or separate opposite ends of the secondnonconductive member 162 through a separate switching structure. In thiscase, a reflection coefficient of each antenna may change as theopposite ends of the second nonconductive member 162 are short-circuitedor opened.

The first antenna 201 shows a reflection coefficient change of a graph410 a while the opposite ends of the second nonconductive member 162 areopened. The first antenna 201 shows a reflection coefficient change of agraph 411 a while the opposite ends of the second nonconductive member162 are short-circuited.

FIG. 5 illustrates changes in radiation characteristics during usercontact with an electronic device, according to an embodiment of thepresent disclosure.

Referring to FIG. 5 , a graph 501 shows a change in radiation efficiencyof the first antenna 201 according to a direction in which the usergrips the electronic device 101, in a pre-switching state (the state ofFIG. 2A).

In the graph 501, before the user grips the electronic device 101, thefirst antenna 201 shows an operating characteristic of the graph 510.The first antenna 201 may transmit and receive a frequency signalincluded in the low band (e.g., the 800 MHz band) or the middle band(e.g., the 1500 MHz band).

When the user grips the electronic device 101 in a first direction(e.g., the user grips the electronic device 101 with his/her righthand), the first antenna 201 shows an operating characteristic of agraph 511.
